The Arelat and the Duchy of Burgundy in the 12th and early 13th century. In northeastern Burgundy, what is now French-speaking Switzerland, the spheres of influence of France and the Holy Roman Empire overlapped. Berthold II lost his title as the Duke of Swabia in 1098, and called himself "Duke of Zähringen" from 1100. His son Conrad I was the rival of Renaud III of Mâcon for the government of the Arelat. Renaud prevailed, though he had to cede large parts of the eastern Transjuranian lands to Conrad, who was made "rector of Burgundy" in 1127 against, setting a precedent of western Switzerland being considered a territory separate from the rest of Burgundy.
